i have a 4thgen and i am getting kSports soon and plan so be riding LOW. i want to get 18X8 and i dont want to worry about rubbing the sidewall. What offset do u recomend to sit just inside the fender???

 

I would go around +35 .... you might want a spacer for the rears if you are running the same wheel front and rear. I thought my Zs 8.5 +40 looked perfect in the front. A 9 with a +34 sticks out a few mm. Remember that the tire size will affect your fitment.

what kind of stagard fitment could i go in the back cuz i dont want to use spacers

 

I'd go 8" front with a +35 and a 9" rear with a +35 that should keep them under the fender but at the edges.... the front and the rears should look even with this setup

 

sweet thanks
